Sapphires - Australia
Information
1. Shipped to Thailand and marketed there as Hai Sapphires
2. Weather out of alkali basalts - apparently
3. Silk in corundum is probably rutile
4. Heat treatment is necessary to remove silk
5. Sri Lanka sapphires are light blue and heated to darken
6. Australian sapphires are dark and heated to remove silk and lighten.

Emerald - Biron Hydrothermal Synthetic
1. Made in Australia, contain water (therefore hydrothermal), and have V & Cr
2. New and first commercially available in 1985; Marketed as Biron
3. Color green to blue green
4. Pleochroism: e ray is blue-green; Oray is yellowish green
*5. Specific Gravity: Biron = > 2.67 like most natural emeralds whereas other synthetics are < 2.67 (Float in 2.67 liquid)
*6. Does not fluoresce red (like others - synthetic) probably due to high vanadium content
*7. R.I. of 1.569 - 1.573 are low, like all synthetics and thus not to be confused with natural emeralds
8. Inclusions of gold and "finger prints" with white particles - distinctive
